Spectrum analyzers are a great way to visualize music, and “TUENHIDIY” came up with an interesting take on this device using not one, but four Arduino Unos. Each board receives the same sound input via a 3.5mm audio jack, and separately processes it to break out the left and right channels, as well as upper and […]
For his school science fair, Mars Kapadia decided to take things up a notch and create his own pair of smart glasses. The project, which went on to place in the state competition, uses a transparent OLED display to show info from Retro Watch software running on an Android phone. The wearable device is controlled by […]
If you’d like to add a gear stick to your virtual race car, then Oli Norwell has just the project for you. His USB device extends a joystick with a length of threaded rod through a custom-cut wooden plate, restricting movements to a 1-5/reverse/neutral layout. The shifter is held in different gear positions using magnets, […]
UPDATE: Both the iOS and Android versions are available and can be downloaded for free from the App Store and Google Play, respectively. The perfect companion to the Arduino IoT Cloud! Develop your IoT solution online via a desktop, then monitor and control your dashboards on your mobile with the new Arduino IoT Cloud Remote […]
When you think of a “7-segment” display, your mind naturally goes to something involving LCD or LED technology. As seen here, however, this 0-9 pattern can also be duplicated mechanically using a series of electromagnets. Neeraj Rane’s 3D-printed device is controlled by an Arduino Nano, along with a shift register. These activate seven hand-wound coils that […]
Inspired by an old FlipFold TV ad, YouTuber Ty Palowski decided to make his own automated shirt folding machine. Palowski’s device is made in four folding sections, which lie flat to accept the unfolded piece of laundry. When the shirt is properly placed, a capacitive touch sensor starts the process, which is controlled via an […]
Troy Hawkins (AKA “tomatoskins”) had come across an interesting wooden perpetual calendar, which used a trio of rings to show the month, day, and day of the week. The only problem is that it’s manually operated, subject to human error or neglect. So when he decided to construct his own version, he added an Arduino to […]
Whether you work in meters, feet, inches, or kilometers — or any number of other units corresponding to properties that you need to convey — conversions are a fact of life when making things. While this could mean pulling up a Google tab or flipping open a Machinery’s Handbook and doing a few hand calculations, […]
For a class project, University of Stuttgart students Ekin Sila Sahin, Lior Skoury, and Simon Treml came up with a unique painting robot named the Physical Twin. The Physical Twin travels on a three-wheeled chassis and mounts a four-axis arm with a brush. An operator controls the arm to dip the brush into an onboard paint container, […]
As you work on a project, lighting needs change dynamically. This can mean manual adjustment after manual adjustment, making do with generalized lighting, or having a helper hold a flashlight. Harry Gao, however, has a different solution in the form of a novel robotic task lamp. Gao’s 3D-printed device uses a USB camera to take images […]
